[BUGFIX] Use correct route path for submodule request

The path for the Belog module changed in v11 and does
now contain the `/module` prefix. Since it's obviously
never a good idea to use such hard-coded values, as can
be seen in this example, the route path is now generated
by the UriBuilder. This will prevent further bugfixes
in case the path structure will change again.

Additionally, the $GLOBALS['TYPO3_REQUEST'] declaration
is removed, since #93853 was already merged.

Resolves: #94018
